Considering a middle housing project? We strongly encourage you to schedule a preapplication conference with our Development Review/Current Planning staff to learn more about the process. Complete the Pre-Application Request Form to get started.
Under state law and Washington County Community Development Code (CDC) standards, middle housing includes duplexes, triplexes, quadplexes, townhouses and cottage clusters that meet certain criteria. Middle housing regulations allow:
- Middle housing in urban unincorporated residential districts where a single-detached houses are allowed: R-5, R-6, R-9, R-15, R-24, R-25+, R-6 NB, R-9 NB, R-15 NB, TO:R9-12, TO: R12-18 and TO: R18-24.
- Find your property’s land use district (Intermap)
- Densities per site greater/higher than those for other housing
- Provisions to make it easier to keep existing homes and Accessory Dwelling Units on a site
- Certain design and siting standards
- At least one off-street parking space per unit
If a tax lot needs to be partitioned, a middle housing land division procedure allows for an expedited process.
